Description
Technical field
The utility model is related to a kind of polished rod sealer, more particularly to a kind of polished rod lubrication and seal device.
Background technology
Rod-pumped well is in normal production process, because the liquid extracted out from underground contains corrosive substance, to polished rod
There is very big corrosivity.If things go on like this.The outer surface of polished rod is just etched into pock-marked face, highly impacts the sealing effect of sealer
Really.Cause oil leak and atmosphere pollution etc. endanger, add Master Cost, due to change packing be well to be stopped also reduce drive a well when
Rate.Packing is provided with inside existing polished rod sealer, before polished rod does not corrode, sealing function can be played, still,
After the outer surface of polished rod is just etched into pock-marked face, the situation of leakage is occurred as soon as, now general settling mode is close in polished rod
Coating butter on the upside of device is sealed, a certain degree of sealing is realized, still, because polished rod is moved up and down, therefore, butter quilt can be made
Take away, cause leakage to run liquid again.
The content of the invention
There is provided a kind of polished rod lubrication and seal aiming at the drawbacks described above that prior art is present for the purpose of this utility model
Device, reduces the labor intensity of employee, reduces the corrosion of polished rod, improves the service life of polished rod.
Its technical scheme is：Sealer body, capping including tubular, clamping head, beam hanger hole, the top of sealer body
Capping is connected through a screw thread, is, with stupefied clamping head, beam hanger hole to be offered on clamping head, in the sealer in capping upper end
Body inner bottom part places circular lower gasket, and lower packing is placed on the top of lower gasket, and righting is placed on the top of lower packing
Seat is fixed with spring on the top of righting seat, and upper packing is placed on spring top, and cylindric pressure cap is placed on upper packing top,
Offer oil filler point on the side wall of the sealer body, polished rod sequentially pass through from top to bottom the intrinsic pressure cap of sealer,
Upper packing, spring, righting seat, lower packing and lower gasket, are connected further to the sucker rod of underground.
Position of the above-mentioned oil filler point on sealer body, is opened between upper packing and lower packing, will by oil filler point
Butter is injected in the cavity between upper packing and lower packing.
The top of above-mentioned righting seat is bulge loop, and the bottom of spring is enclosed on bulge loop.
The beneficial effects of the utility model are：The device be provided with spring, polished rod by sealer centre bore up and down reciprocatingly
Motion process, the elastic feature having by spring, packing is extruded, and is made sealer sealing close, is reduced the tight disk of employee
The number of times of root, reduces the labor intensity of employee.The device is provided with oil filler point, and butter is injected into upper packing with by oil filler point
In cavity between packing, the abundant contact of butter and polished rod reduces the corrosion of polished rod, improves the service life of polished rod；This reality
With the new corrosion for reducing the labor intensity of employee, reducing polished rod, the service life of polished rod is improved.
Brief description of the drawings
